How do they measure cup pressure
Posts: 1,558. C.U.P is measured with a copper crusher. Basically it is a hole precisely drilled into the chamber of the test gun. The hole is there to accept a copper pellet that is measured before and after the cartridge is fired. The amount of difference in length of the copper pellet is used to calculate the pressure.

High Pressure Grinding Rolls
CRITICAL HPGR PARAMETERS. HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. Typical HPGR throughput rates range from 20 to 3,000 tph, with installed motor power as high as 3,000 kW per roll.
How it Works: Crushers, Grinding Mills and Pulverizers
Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.

Aluminum vs Copper Crush Washers: 6 Differences Revealed!
In terms of strength, the copper is a clever winner here. The tensile strength of copper is 380 MPa or 55,114 psi. On the other hand, the tensile strength of aluminum is up to 200 MPa, or 29,000 psi. That means copper can hold up to 55,000 pounds per square inch of pressure, whereas aluminum can hold up to 29,000 pounds per square …
